This directive is useful for cutting sections of audio out in
addition to making it easier to share track offsets between
different recordings of the same source.
|
|
Similar to the switch in dtas-archive(1), I got tired of having
to manually add stats to all the rips I was tracking out.
|
|
When this project started avconv was favored in Debian,
but that hasn't been the case in many years. Increase
the priority of ffmpeg to match the current situation in
Debian.
|
|
Sometimes I only want to archive files matching a certain regexp pattern.
|
|
--filter, per-track comments and environments are the subtle but
major new features for the next release.
|
|
This helps for folks creating and replacing many throwaway files
while editing with dtas-splitfx, or compulsive renamers.
|
|
"omap" is specific to Ruby and makes interopability with other
languages more difficult.
While it's true environment variables are stored as an ordered
array of C strings (see environ(7)); order doesn't matter in
practice. Everyone in the real world treats the environment as
an unordered key-value store, and we shall follow.
|
|
Write the contents of "stderr". This is useful for capturing the
per-track output of the sox(1) "stats" effect when combined with
parallel "--jobs".

sleepy_penguin is still a hair faster than libffi+fiddle,
but most users probably won't notice. So stop documenting
it, but just don't introduce performance regressions for
existing users.

lists.gnu.org is no longer accessible via FTP.

touch(1posix) documents the presence of "-r"

HTTPS allows some level of security(*) and we've actually
supported it on 80x24.org for many months, now. So, point new
readers to it.
Moving away from hostname-based homepages will allow us to save
on subjectAltName space (and bandwith) when negotiating an HTTPS
connection. We'll also have an .onion mirror for Tor users,
soon, too; in case we can't afford to pay ICANN in the future.
(assuming TLS libraries don't have any more Heartblead-level
bugs in them, CAs aren't compromised, MITM HTTPS stripping
proxies don't get in your way, and your certificate bundle isn't
compromised).

|
These commands allow easier jumping within a track marked by
embedded CUE sheets. I've found them helpful for tracking out
large recordings of multiple tracks (e.g. vinyl transfers or
live concert recordings).
|
|
shuffle was never documented in dtas-tl(1) when it was introduced,
and consume is a new feature.
|
|
We should not be busting caches and wasting visitor's bandwidth
for unmodified files.

perlpod(1) is already installed by default on Debian and
RedHat-based systems; and probably most modern *nixes; pandoc(1)
(and Haskell) are not.
POD also more standardized than Markdown (which flavor? :P),
especially for generating manpages. So save any potential
documentation editors some disk space by not forcing them to install
Haskell and pandoc.
Finally, I'm a mildly proficient in Perl and do not know Haskell
at all and have a better chance at reading/hacking the source if
the document generator breaks.

|
Oops :x
|
|
Note to self: remember to document new features as they're added.

We removed support for opusenc back in May as it was not
really suitable for audio production and a maintenance burden.
ref: commit 7ca5d0bfc714c254c374af9cbc2e024a8b439725
("splitfx: remove support for encoding opus")

English grammar is not easy :x
While we're at it, dtas-archive.txt is expanded to document things
like: http://80x24.org/dtas-all/20150918085401.GA8610@dcvr.yhbt.net/
(bus failure).
|
|
While we're in the area, make a wording change from "GPLv3 or later"
to "GPL-3.0+", as the latter is favored by SPDX.org
|
|
This is on a linear scale from 0.0 (mute) to 1.0 (no change)
This is in the MPRIS spec and mpd as well (scaled to 0-100)
This changes dtas-console key bindings (0/9) slightly to match
mplayer more closely. ReplayGain preamp adjustment has moved from
'0'/'9' to '7'/'8' keys. The 'm' key also toggles mute state (the
pre-mute volume is stored in the dtas-console instance, not in
dtas-player itself).

|
This should allow convenient rearranging and deleting of tracks from
the tracklist from your favorite $EDITOR.
|
|
It makes more sense to return the previous value
rather than the newly-set one, since the user presumably
knows what they're setting and might care about the
previous value.
|
|
The dpc_tl method was becoming too large, split it up into
sub-methods for easier readability. While we're at it,
at least make "tl repeat" consistent with "tl shuffle"
when setting new values.
|
|
Not everybody cares for manpages.
|
|
This will dump the contents of the current queue, including
positional seeking information and commands. This is mainly
intended for debugging and tools which rely on dtas internals.
|
|
This allows splitfx YAML files to operate more seamlessly with
external commands such as play(1) especially when combined with
the -t/--trim option.
|
|
It can be useful to display time as absolute seconds to
ease arithmetic for tracking files.
|
|
It can often be useful to expose only part of a track for quick
inspection. This lets us do that.
|
|
generic targets (e.g. "wav") is useful for quickly checking if
clipping is introduced by dither and resampling, so we'll support
changing the sample rate and bits-per-sample from the command-line
so users don't need to setup their own targets or wait on FLAC
encoding.
|
|
This can be useful for speeding up splitfx during development,
as sox defaults to maximum compression with FLAC and that is
extremely slow.
|
|
Followup-to commit 403ed90e2e7bed3e017938d76e17037b0d5059b6
(replaygain uses the "gain" effect instead of "vol")
The `gain' effect seems superior as it can "see" across the effects
chain to take into account extra/lost headroom.
|
|
It is useful to force output to a writable directory if the YAML
file is on a read-only mount point or to force the output to a
large tmpfs mount point to avoid SSD/HDD wear.
|
|
New features need to be documented.
|
|
This archives audio files (typically .wav from a portable devices)
as FLAC and performs a best-effort verification the file was
transferred succesfully without bit errors by dropping kernel caches
and rechecking the result.
|
|
This feature is intended to allow users to "zoom-in" on a
particular portion of a track to tweak parameters (either
with dtas-sourceedit(1) or via playback of splitfx YAML files).
This may be combined with looping the tracklist
(via "tl repeat").
|
|
While the Ruby Hash class is ordered in 1.9+, the YAML
specifications do not specify hashes as ordered by default.
Thus we must explicitly declare ordering via !omap for
interopability with non-Ruby tools.
This makes the YAML output of dtas-sourcedit and dtas-sinkedit
slightly more verbose
Users of dtas-splitfx are also encouraged to declare !omap
when creating their YAML files for interoperability.
Ordering env is important because any implementation of
built-in variable expansion is dependent on it.
|
|
The documentation part is managed by the new
Documentation/update-copyright script. For the future, the rest may
be managed by the update-copyright tool in gnulib
|
|
These are the raw sample counts for the "trim" effect
and may be useful for arithmetic in the shell.
|
|
This rounds out the documentation a bit and hopefully
introduces/encourages some commonality between the playback
and processing/production components of dtas.
Clarify some splitfx-related environment variables while
we're at it.

This allows changes in the source YAML file to be reflected
immediately in player after the user saves the file in their
favorite $EDITOR. Previously, a user would need to:
1) start dtas-sourceedit, spawning $EDITOR
2) edit the file
3) save changes
4) exit $EDITOR
5) repeat starting from 1) until happy with the results
Now, the workflow allows avoiding the context switch between their
$EDITOR and terminal to restart dtas-sourcedit:
1) start dtas-sourceedit, spawning $EDITOR
2) edit the file
3) save changes
4) repeat starting from 1) until happy with the results
5) exit $EDITOR
In my experience, this greatly speeds up tuning of the playback
change, giving all the repeatability and flexibility of editing text
files while having the immediacy of an interactive UI.
Keep in mind this can cause problems for those with auto-save
enabled in their $EDITOR buffer at inopportune times, so a
-N/--no-watch option is added.
|
|
These are intended to act like `$(@D)' and `$(@F)' in GNU make(1)
and to ease managing temporary files for some effects
(e.g. noiseprof + noisered in sox) for splitfx users.
|
|
While we're at it, document the splitfx manpage and
make the example suitable for tests.
|
|
This becomes useful for systems without inotify when we're editing
YAML (or whatever) files frequently and want changes to be reflected
right away during playback. This is a weaker version of the plain
"restart" command, which restarts the entire playback chain.

The following subcommands are now documented:
* current
* current-id
* next
* prev
